To all whom it may concern:

Be it known that I, Ennsr SoHnLLHAss, a subject of the German Emperor,and residing at Berlin, Germany, have invented certain new and usefulImprovements in Conveyor Apparatus for Feeding Bars of Metal to andDelivering the Same from Machines, of which the following is aspeclfication. v

The present invention relates to improvements in conveyers especiallyadapted for feeding bars of metal, or girders to a drilhng or othermetal working machine,.and particularly to means whereby the artlcles tobe operated on by such machine are delivered or fed to such conveyer. Inaccordance with this invention a series of the articles to betransported by the conveyer are stacked upon a suitable stationarysupport arranged at one side of the conveyer and means are provided bywhich said articles are successively removed from the stack and deposited on the conveyer, such means belng controlled by a single handlever.

In the accompanying drawings, Figure 1 is a front elevation of aconveyer such as hereinbefore referred to and means for deliveringarticles thereto embodying the present invention; Fig. 2 is a verticaltransverse sectional view through the conveyer and such feeding means;Figs. 3, 1 and 5 illustrate in elevation, plan and detail section theclutch mechanism employed for connecting the feeding devices with adriver; Fig. 6 illustrates a slight modification.

Referring to the drawings, 1, 2, designate a pair of supporting beams onwhich are arranged a series of transverse beams 3 constituting astationary support for the articles to be transported by the conveyerwhich in the embodiment of the invention illustrated are I-beams 1. Asshown the members 3 of said support are arranged in an inclined positionand provided at their lower ends with upwardly projecting stops 5against which the lower one of the series of beams t bears.

The particular form of conveyer illustrated comprises a series of rolls20 mounted on shafts 2O supported by suitable uprights or standards andthe several shafts are connected by chain and sprocket gearing so thatarticles deposited thereon will be carried toward a suitable metalworking machine, such as is conventionally illustrated at 21.

Between the aforesaid stationary support for the articles to betransported and said conveyer are pivotally mounted a series of arms 9adapted to be held in the position shown in full linesin Fig. 2 to forman inclined way or slide extending from said support to the conveyer andto rock about their pivotal support so as to deposit on the conveyerarticles previously supported by them. As shown, said arms 9 are mountedto rock about a shaft 8, which is supported in suitable bearings 7provided at the upper ends of frame 6 and the lower end of each arm isadapted to be engaged by a suitable latch which acts to hold the arm inthe full line position, shown in Fig. 2. As shown, such latch consistsof a lever 11 mounted to rock about an axis 10 and having its upper end11 extending longitudinally of the adjacent arm 9. In one edge saidlever 11 is provided with a notch 12 adapted to receive a pin or stud 18projecting laterally from the adjacent arm 9 and said latch lever is soweighted and constructed that it automatically tends to engage the pin13 and thus hold the lower end of the arm 9 against movement thereby providing afirm guideway over which the beams 4 can move.

The beams 4 are successively transferred from the stationary support 3to the in clined slide or guideway formed by the arms 9 by the action ofa series of disks 22 se cured to the shaft 8 and each having a camshaped periphery providing a member 22 adapted as the shaft 8 rotates toengage a flange of the lowest beam 4 of the series and lift the sameover the stops 5 and push it on to the slide 9. As the beam passes downthe slide it will strike the upper ends 11 of the latches 11 withsufficient force to rock said latches and disengage the pins 13 from thenotches 12. As soon as the arms 9 are thus released they will under theweight of the beam supported thereby rock downwardly about their axialsupport and the beam will thereby be deposited upon the conveyer rolls20 in proper position to be fed to the machine 21. The shaft 8 isadapted to be clutched to a suitable driver by means permitting it tomake but a single revolution and then be automatically disconnected.This clutch mechanism and the means by which an operator can control theaction thereof is illustrated particularly in Figs. 3,

4 and 5 referring to which it will be seen that the clutch 28, comprisesa driving member 58 which may rotate constantly and a member 57 which isconnected with the shaft 8 by means hereinafter more particularlydescribed adapted to be engaged with said member 58 by the operation ofa hand lever 24. Said lever 24 is pivotally mounted at 28 and near itsupper end is provided with a latch member 48 having a link 49terminating in a pin 49 that projects into a slot 49 in said lever andadapted as the latch is rocked to be moved to and from a position whereitwill engage with a shoulder 50 on a reciprocating member 51 having itsend adjacent the shaft 8 bifurcated and terminating in two forked arms54, 59, arranged respectively above and below the horizontal plane ofsaid shaft. A stop 52 cooperating with a shoulder 60 on the slide 51acts to normally hold said slide in the position shown in Figs. 3 and 4in which position a pin carried by an arm 55 secured on the shaft 8engages the fork 54. The arm 55 is not connected directly to the shaft 8but to a threaded sleeve 56 which is revoluble on said shaft and whichthreaded sleeve is engaged by the hub of the movable clutch member 57.By manipulating the latch 48 to move the pin 49 upwardly in the slot inthe operating lever 24 and shifting said lever from the position I, Fig.8, to the full line position II in said figure, the slide 51 can berocked sufiiciently to disengage the nose 60 thereon from the stop 52and by then returning said lever to the position I, the arm 55 will berocked and the clutch member 57 engaged with the driving member 58. Theshaft will thereby be caused to rotate and through the disks 22 transfera beam 4 from the stationary support to the inclined feed slide 9. Asthe shaft rotates the pin 53 on the arm will be moved out of engagementwith the for: 54 and will subsequently engage the lower fork 59, therebymoving the slide 51 in the reverse direction and bringing the projection60 in front of the stop 52. The lever 24 is retained in the position I,it being understood that the latch 48 is released and the pin 49returned to its original position as soon as the slide 51 has beendisengaged from the stop 52 at the time of moving the lever 24 fromposition II to position I. The continued turning of the shaft 8 willcarry the pin 58 from the fork 59 and into the fork 54 or the positionshown in Fig. 3 and by the engagement of said pin with the latter forkthe rotation of said arm 55 will be checked, the slide 51 being at thistime held (station ary by the action of the stop 52. Conse quently thesleeve 56 will be turned sufficient to disengage the clutch members 57,58, and the shaft 8 will be held stationary until the lever 24 is againoperated.

In order not to interfere with the feeding movement of the beam 4 by theconveyer rolls, means are provided whereby the arms 9 and latch levers11 are retained in the position indicated in dotted lines in Fig. 2,which are assumed during the operation of delivering a beam to theconveyer, until said beam has been transported beyond the paths ofmovement of said arms and levers. The particular stop mechanism employedfor this purpose in the embodiment of the invention illustrated isdesignated as a whole by the reference character 15 and comprises twomembers 15 pivot-ally mounted on a suitable axis 16 and providedrespectively with fingers or tappets 17, 18. Each of said stop membersis so weighted as to automatically tend to assume the position indicatedin Fig. 2 and a slot 30 is formed through the lower portions of saidmembers and into said slot extends a pin 29 on a swinging arm 27 whichis connected by links 25, 26, with the lever 24 or the shaft 28 on whichsaid lever is mounted.

Referring to Fig. 2 it will be seen that when the beam 4 slides down theinclined guideway 9 and strikes the head 11- of the latch lever 11, saidlever will be rocked to carry a projection 19 thereon beyond and intoengaging position with the tappet 18. During the movement of the latchlever 11 from the position indicated in full lines in said figure tothat represented in dotted lines, the tappet 18 will swing about theaxis 16 but will immediately return to the position shown in Fig. 2 andby reason of the pin 29 engaging the right hand side of the slide 30will actto positively prevent return of the lever 11 to its full lineposition. Similarly the downward movement of the arm 9 will rock thetappet 17 about the axis 16 and such tappet will automatically assumethe position shown in Fig. 2 where the arm 9 is prevented from upwardmovement by reason of the engagement of the pin 29 with the right handend of the slot 80 in the support for the tappet 17. The parts will beretained in this position while the lever 24 occupies the position Iindicated. When, however, said lever is returned to position II the pin29 will be shifted to the opposite end of the slot 30 and the arms 9 canthen return to their elevated position under the action ofcounter-weights 14 connected therewith and the latch levers 11 will alsoreturn to the position indicated in full lines in Fig. 2 in which theyengage the pins 13 on said arms 9, as before described.

Instead of employing counter-weights 14 to return the arms 9 to theoperative position, said arms may be positively rocked from the shaft 8,as illustrated in Fig. 6. In this construction the rearwardly extend ingmember of each arm 9 is connected by a link e with an arm (Z of a bellcrank lever fulcrumed at Z) upon a bracket a on the standard (3. Theother arm 0 of said bell crank lever extends into the path of rotationof a pin or stud f on the adjacent disk 22. Thereby as the shaft 8 isrotated to remove a beam from the stationary support the arms 9 arepositively rocked upwardly into position to form the inclined feed guideand are retained in this position by the latches 11 after the pin f haspassed from engagement with the arm 0 of said bell crank lever.
